One example is the bulldozing of the historically Black Albina neighborhood in North and Northeast Portland in the 1950s and 1960s to construct the Interstate 5 highway. A governmental decision to place the highway in that location demolished more than 300 homes in Lower Albina. Two thirds of the 3,000 people who lived there were Black, in part due to racial segregation. The freeway’s placement split the neighborhood in half, and increased car traffic led to more pollution felt primarily by the Black residents remaining in the area. Local organizations like the Albina Vision Trust are now leading reinvestment and reenvisioning of the neighborhood from this harm.
